Abstract: Provided is a heat storage device which can stably store heat by storing heat within a fixed temperature range. A heat storage device (10) of the present invention is characterized in being provided with a heat resistant frame (11), which is filled with one kind of alloy or mixed salt having a predetermined eutectic temperature, alternatively, a heat resistant frame (11), which is filled with two or more kinds of alloys or mixed salts having different eutectic temperatures, by having the alloys or the mixed salts adjacent to each other in the order of eutectic temperature levels with a partitioning wall (11a) therebetween.

Abstract: A device having a tube for heating or heat retaining of fluid includes a first path in which a connection section of a cord heater led out of the tube and a lead wire connected to a power supply is provided, a second path provided between the tube and the first path, and a drainage path for removing leaked fluid of the second path. In this device, the connection section is sandwiched by a pair of first sealing members to retain a sealed state and the cord heater passes through the second path in a sealed state by a second sealing member. This device can effectively prevent gas or liquid from leaking into the space where the connection section of a lead wire and a cord heater is provided.

Abstract: A connection-state check tool is used for assembling a pipe coupling having a connection pipe and a coupling member. The connection-state check tool comprises a pair of arms and a frame-shaped handle. The pair of arms has claws that can clamp down on the coupling member, and are engageable with the connecting pipe. The frame-shaped handle is connected to the arms. The handle has a split at a position opposite to the arms. The handle has elasticity, due to which the split can expand.

Abstract: The present invention makes a proposal of a heating component for a pipe joint which can be easily mounted on a pipe joint and also can stabilize the assembly quality to the pipe joint. The heating component for a pipe joint is characterized in that the heating component for a pipe joint has partially thereon fitting portions each having an inner face shape fitted with a part of an outer shape of the pipe joint, and also, a holding recess portion for holding therein a heating wire is formed on an inner face portion other than the fitting portions; when the heating wire is held in the holding recess portion, and then, the heating component for piping joint is mounted to the joint by fitting the fitting portions with the parts of the outer shape of the joint, the heating wire held in the holding recess portion comes in contact with the pipe joint.

Abstract: A quick connector includes a female pipe having a flange in the outer peripheral part thereof, a male pipe having a retainer mounting part, and a retainer slidably mounted on the retainer mounting part of the male pipe to slide at a right angle to the axial direction of the male pipe, in which the female pipe and the male pipe are connected with each other by the retainer holding the flange of the female pipe, and the retainer is allowed to move from a temporarily fixed position to a completely pushed-in position on the retainer mounting part only when the female pipe and the male pipe are in a completely connected state, so that a worker can easily and reliably check whether the pipes are in an incompletely connected state or in a completely connected state by means of hand feeling only without relying on a visual check.

Abstract: A problem solved by this invention is to enable prevention of damage to a connector in a fluid transfer tube that is made by mounting a connector to an end of a tube, even when an outside air temperature falls below freezing point. The problem is solved as follows. In a fluid transfer tube that is made by mounting pipe joints to ends of a tube that has elasticity, tube connecting portions of the pipe joints and sections of the tube in the vicinity of the tube connecting portions are covered with heat radiation preventing covers to thereby delay freezing of a fluid inside the tube sections that are covered by the heat radiation preventing covers.

Abstract: A piping structure of a tube for heating or heat-retaining of fluid such as gas and liquid includes a conduit through which fluid is transported and a plurality of heater lines inserted into the conduit, in which the heater lines are connected in parallel. The piping structure is capable of transporting fluid over a long distance while heating the fluid or keeping the temperature of the heated fluid constant even when the total piping length is long.

Abstract: The life log or journal is directed to produce a record of the life of a child by parent and child, explicitly divided into a fetus era, newborn era, school era, grown-up era, and mature-age era, guiding a parent to write down a record when the child is too young to write for himself/herself, and guiding the child to write for himself/herself when the child grows up. In the region guiding the parent to write down a record, an instruction is printed to inspire the parent to facilitate writing down events of the child's development on occasion together with the parent's feelings at that time. As a result, a life log can be produced, leaving the affection devoted from the parent to child in a visual form so that the parent and child can share affection, joy and emotions throughout the childhood and adulthood of the child.
